Type I respiratory failure is characterized by hypoxemia-damaged lung tissue. Type II respiratory failure, or ventilation failure, is characterized by hypercapnia, high levels of carbon dioxide in the circulating blood, or respiratory acidosis, which can be fatal if untreated. Type III respiratory failure involves perioperative atelectasis. Type IV occurs following intubation and recovery from hypoperfused state.
May be classified as an acute, severe, sudden-onset medical emergency, or as chronic, which develops over a period of time and necessitates long-term treatment, such as in association with COPD or chronic drug- or alcohol-induced respiratory suppression. Common signs and symptoms include dyspnea, tachypnea, cyanosis, lung crackles, and altered mental status. Depending on root cause of respiratory failure, treatments include treating the causative disease, oxygen therapy, mechanical ventilation, and tracheotomy.
